People inevitably experience various illnesses in their daily lives and require medication for treatment. The quality of medication directly affects human health, making it essential to strictly control the quality of packaging materials for medicines.
It is necessary to select packaging materials for medicines based on the medicinal properties of the medication to avoid the loss of medicinal properties due to packaging materials. Of course, it is essential not to falsify the quality of pharma packaging material.
Characteristics of glass packing material used in pharmaceutical and their impact on medication quality
Characteristics of glass pharma packing material
Glass packaging materials for medicines are commonly used in medications. It has stability and does not react with medication chemically. It also has excellent barrier properties, which prevent medication from contact with the air outside. Its chemical properties can also be adjusted based on different compositions. It is low in price, aesthetically pleasing, and recyclable.
Impact of glass packaging materials for medicines on medication quality
Firstly, the glass packaging materials for medicines used in infusion cannot be flattened. Therefore, air needs to be introduced into the glass bottle to increase the pressure for infusion. However, during the air intake process, there is a high probability that dust and microorganisms in the air will be brought into the bottle, causing infusion contamination and reducing the medication's effectiveness. Secondly, the glass material may crack or break during its production and transportation process, which makes it susceptible to fungal infection. Finally, some medications may chemically react with glass packaging materials for medicines, rendering the medication ineffective. For example, insulin cannot be used with glass material as it reacts chemically with silica and boron oxide in the glass.
Characteristics of rubber packaging materials for medicines and their impact on medication quality
Characteristics of rubber packaging materials for medicines
Rubber packaging materials for medicines are generally used for medication container stoppers, gaskets, etc. It can be divided into natural rubber and butyl rubber. Natural rubber has a fast aging speed, inadequate sealing performance, and the manufacturing process includes many additional agents, such as β-thiophene biphenyl thiazole, so it cannot be used for medication packaging. Butyl rubber is a copolymer of isobutylene and a small amount of isoprene (≤3%), which is synthesized under ultra-low temperature (-95℃) conditions. Butyl rubber has good air-tightness, acid and alkali resistance, heat resistance, etc., and is suitable for medication sealing.
Impact of rubber packaging materials for medicines on medication quality
Although butyl rubber has stable chemical properties, its composition is too complex. If the formula is not reasonable, impurities in the medical rubber stopper may chemically react with the medication during the contact process, affecting the performance of the injection fluid.
